Nakime

Blood Demon Art: Castle Manipulation

Nakime's Blood Demon Art lets her reshape and relocate the endless corridors of Muzan's Infinity Castle simply by plucking her biwa's strings, transporting allies, separating enemies, or sealing off entire rooms. She was promoted to Upper Moon Four after Hantengu's death and remains undefeated as Infinity Castle Part 1 ends.

Nakime is a demon woman with long black hair covering one eye, dressed in dark, ornate robes, and she is rarely seen apart from the biwa she cradles and plays constantly.

Nakime is detached and unnervingly calm, speaking rarely and betraying almost no emotion even in Muzan's presence, whom she serves with total, silent devotion.
